[0002] In ships, pumps and valves are essential equipment. A large number of pumps and valves are used in conjunction with pipelines. In the pump and valve production process, the valve sealing must be tested after assembly to verify whether there is zero leakage under the valve set pressure to avoid water leakage in the pump and valve.

[0003] According to the existing patent document with publication number CN218156713U, a hydraulic pressure device for testing shaft seal water for pump valves is disclosed. The device includes a water tank assembly, a sealing test assembly is installed inside the water tank assembly, and the sealing test assembly includes a valve, and a left valve port and a right valve port are respectively provided on the left and right sides of the valve. An air filling assembly and a pushing assembly installed on the air filling assembly are installed on the left side of the left valve port. The water tank assembly includes a water tank, and a water tank is provided inside the water tank. A cylindrical groove is provided on the left side of the water tank. A fixing member and a first sealing plug fixedly installed on the left side of the fixing member are fixedly installed on the right side of the water tank. When this technical solution is in use, gas enters the valve body from the air filling pipe, and the pressure gauge can be observed to continue to test the air filling inside the valve body. The sealing of the valve body can be checked by observing whether there are bubbles in the water. With respect to the above technical solution, although this solution realizes the air intake detection of the valve body, it is unable to quickly limit and fix the valve body during the detection, and the valve body cannot be secondary sealed and limited at the same time, which is inconvenient during use.

Later, the ring seat and the fixed tube enter the interior of one end of the valve body, and the valve body is limited by the fixed tube. Later, the movable seat moves to squeeze and fix the valve body between the fixed seats. Later, air is taken in from the inside of the fixed tube.

While the ring seat moves, it produces an extrusion seal with one end of the valve body. The ring seat and the elastic seat cooperate to complete the double sealing of the valve body, avoiding the impact caused by gas leakage during detection. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0027] See also Figures 1 to 6 The present invention provides a technical solution: a pump valve shaft seal water pressure test detection device, comprising a box body 1, a partition plate 2 is fixed inside the box body 1, the partition plate 2 is opened, and a movable plate 29 is movably installed inside the opening, and a displacement mechanism 5 and a positioning column 4 are respectively fixed on the movable plate 29, and one end of the positioning column 4 is movably installed with a positioning tube 3, and the positioning tube 3 and the displacement mechanism 5 are both fixed to the side of the box body 1. A pushing mechanism 6 is fixedly installed on the side of the box body 1, and a fixing component 10 is installed on the pushing mechanism 6. A valve body 9 is movably installed between the fixing components 10. A cavity 8 is opened inside the box body 1, and the valve body 9 is movably installed inside the cavity 8 through the fixing component 10. The displacement mechanism 5 and the pushing mechanism 6 are both linear reciprocating electric push rods. The displacement mechanism 5 pushes the movable plate 29 into the partition plate 2 to seal the opening. One end of the movable plate 29 facilitates moving the valve body 9 to the inside of the cavity 8 while completing the control of drainage.

[0028] In this embodiment, the fixing assembly 10 includes a movable seat 11 and a fixed seat 13. The movable seat 11 is installed on the pushing mechanism 6 through a movable column 12. The fixed seat 13 is fixed to the inner wall of the box body 1. A water pipe 7 is fixed on the side of the box body 1. A connecting pipe 14 is fixedly installed on the fixed seat 13. A pressure gauge 15 is fixedly installed on one end of the connecting pipe 14. An air intake pipe 16 is fixedly installed on one end of the fixed seat 13. A ring seat 17 is movably installed on the fixed seat 13. A movable pipe 18 is fixed on the ring seat 17. A fixing ring 19 and a support ring 20 are fixed on the movable pipe 18. An elastic seat 21 is fixed between the fixing ring 19 and the support ring 20. A limiting tube 25 is fixed on the fixing ring 19. An opening 26 is opened on the limiting tube 25. The opening 26 facilitates the movement of gas to the inside of the elastic seat 21. Later, under the push of air pressure, the elastic seat is inflated and deformed to complete the sealing between the valve body 9 and the fixed tube 18.

[0029] The cam 25 is provided with a plurality of springs, each of which is provided with a plurality of springs, and the plurality of springs are provided with a plurality of springs.

[0030] In this embodiment, a support rod 36 is welded on the inner wall of the movable plate 29, a lifting mechanism 37 is fixedly installed on the support rod 36, a limiting column 35 is fixed on the lifting mechanism 37, a fixing frame 38 is fixed on the lifting mechanism 37, one end of the fixing frame 38 is fixed on the cross bar 34, the cross bar 34 and the limiting column 35 are movably mounted on the side of the valve body 9, a bottom plate 39 is fixed inside the cavity 8, a through hole 40 is opened on the bottom plate 39, a conical seat 41 is fixed inside the box body 1, the An exhaust fan 42 is fixed inside the conical seat 41, and a connecting hole 43 is opened between the partition plate 2 and the cavity 8. An elastic plate 44 and a baffle 45 are fixed on the inner wall of the connecting hole 43 respectively. The baffle 45 is movably installed on the side of the elastic plate 44. The lifting mechanism 37 is a linear reciprocating electric push rod. The lifting mechanism 37 pushes the cross bar 34 and the limit column 35 to move up and down. The up and down movement of the cross bar 34 and the limit column 35 completes the up and down adjustment of the height of the valve body 9, so that the two ends of the valve body 9 are distributed in the same center as the movable seat 11.

[0031] Before using the device, the movable plate 29 is separated from the partition plate 2, the fixed assembly 10 is moved to the top of the conical seat 41, and the valve body 9 is horizontally moved to the inside of the fixed assembly 10 through the slot on the side of the box body 1. The valve body 9 is suspended and installed on the cross bar 34 and the limit column 35. The displacement mechanism 5 is started to push the movable plate 29 to move. After the movable plate 29 moves to the partition plate 2, the fixed assembly 10 moves to the inside of the cavity 8. The lifting mechanism 37 is started to control the up and down movement of the valve body 9. The up and down movement of the valve body 9 is quickly aligned with the movable seat 11 and the fixed seat 13. Before the fixed assembly 10 enters the cavity 8, the annular seat 17 is pushed with The movable tube 18 moves toward the direction of the air inlet pipe 16, so that the space between the ring seat 17 and the movable seat 11 is opened. When the valve body 9 moves to the inside of the cavity 8, the ring seat 17 is released, and the fixed ring 19 is pushed outward by the support mechanism 24. The fixed ring 19 drives the support ring 20 to enter the interior of the valve body 9 through the elastic plate 21. The fixed ring 19 and the support ring 20 cooperate to complete the initial support of the valve body 9, and then the pushing mechanism 6 is started. The pushing mechanism 6 pushes the tapered column on the movable seat 11 to enter the other end of the valve body 9. As the movable seat 11 moves, the movable seat 11 pushes the ring seat 17 at one end of the valve body 9 to move. When the ring seat 17 moves, one end of the limiting tube 25 cooperates with one end of the fixing seat 13 to stop moving. The limiting tube 25 moves the fixing ring 19, which pushes the support column 22 to move inside the support tube 23. The movement causes the elastic seat 21 to arch upward and contact and seal with the inner wall of the valve body 9. Then, external gas enters the interior of the valve body 9 through the air inlet pipe 16. As the air pressure inside the valve body 9 increases, the gas enters the position of the elastic seat 21 through the opening 26. The elastic seat 21 is deformed after being inflated. After the deformation, the elastic seat 21 increases the contact area with the inner wall of the valve body 9, thereby completing a better seal. Water enters the water pipe 7 while inflating. Water moves upward through the through hole 40 on the bottom plate 39, and the water surface submerges the valve body 9, so that the valve body 9 is observed to be leaking based on the water. After the detection is completed, the water pipe 7 is discharged outward, and the displacement mechanism 5 drives the movable plate 29 to move. After the movable plate 29 moves, the opening is opened, and the water inside the cavity 8 is discharged through the opening at the same time, which facilitates the outward movement of water. After the movable plate 29 moves the fixed component 10 to the top of the conical seat 41, the exhaust fan 42 blows air upward to quickly dry the surface of the valve body 9. The water staying inside the conical seat 21 later pushes the elastic plate 44 to tilt and enters the bottom of the bottom plate 39 for later discharge.
